The way you know.
The way you control.
The network is slow. Every utilisation graph is green. Nobody can explain it. Net-Monitor reads the real traffic on the wire — not just device counters — and its AI finds the cause while everything else still looks fine.
Runs against your existing network · Nothing to install on your servers
Trusted across finance and insurance, high-tech, industry and services, and government and public institutions.
Everything is slow.
Nothing is busy.
This is the call every network team dreads — because the usual answer is not there. No link is saturated. No device is at its limit. And yet the business is grinding.
- 09:14Users say everything is slow.
- 09:31Every graph says the network is fine.
- 13:50Someone finds it. By accident.
Utilisation is the easy answer, and most of the time it is the wrong one. Net-Monitor was built for the other case — the one your current tools cannot see.
The link is not full.
So why is everything slow?
Nearly every monitoring product watches the same thing: device counters. When those look fine, it has nothing left to tell you. Net-Monitor goes a level deeper and reads the real traffic on the wire — which is where the answer actually is.
Every router, switch and server checked continuously — availability, response time, port status and errors, across every vendor you own.
Turns a link into names: which users, which applications, which servers are talking to each other, and how that pattern changes.
The sniffer records the packets themselves. Delay, retransmission, failed handshakes, sessions falling over — the things that make a network feel broken while every counter reads normal.
All three answers together, checked against what normal looks like for you — so you get the problem and the cause, not just a red icon.

Most tools stop here. This is table stakes.
Turns a link into names: which users, which applications, which servers are talking to each other, and how that pattern changes.
Useful context — but it still cannot tell you why anything is slow.
The sniffer records the packets themselves. Delay, retransmission, failed handshakes, sessions falling over — the things that make a network feel broken while every counter reads normal.
Sniffer recording packets is the layer almost nobody else has. It is the only place the answer lives.
Less downtime
Problems are caught while they are still forming, so most never reach your users at all.
Faster resolution
Every alert arrives with the cause attached, turning long investigations into short fixes.
Fewer surprises
One live picture of every device, link and application — no blind spots between vendors or sites.
Lower cost
Spend on the capacity you actually need, and run the whole thing with a small team.
Watch the two stories separate.
Drag the timeline. The lower track is link utilisation — flat, comfortable, never near its alert limit for the entire incident. The upper track is what your users are actually living through. Every utilisation-based tool in the building is looking at the bottom line and reporting green.
- Finds problems that never show up as load
- Learns your network instead of waiting for a limit
- Every alert arrives with the cause already identified
- Keeps the evidence, so you can answer questions later
Net-Monitor has learned what this part of your network normally does at this time of day. Traffic is comfortable, the wire is clean, and nobody needs to be told anything.

Utilisation is comfortable and the wire is clean.
Five jobs, off your team's plate.
Works with the mixed-vendor network you already have — from one site to many, without agents to install or a rebuild to plan.
Everything your team needs. One screen.
No more jumping between tools to answer a single question. Your map, your traffic, your alerts and your configuration changes all live in the same place.

Illustrative views representing Net-Monitor output.
Powerful underneath. Simple to live with.
Quick to deploy, easy to run, and built to give your team answers — not another dashboard somebody has to watch.
We see what other tools miss
Most platforms only read device counters. Net-Monitor also reads the real traffic on the wire, so you get the actual cause instead of another red icon.
Running in days, not months
Nothing to install on your servers and no agents to roll out. It works with the network you already have, so you see value in the first week.
Everything on one screen
Live maps, graphs and dashboards of your whole estate, built automatically. No more switching between five tools to answer one question.
Fix faster, not just find faster
Net-Monitor points at the root cause and shortens time to resolution. Your team spends its day fixing problems instead of hunting for them.
Works with every vendor you own
Standards-based and multi-vendor from day one. Mixed estates, many sites, thousands of ports — all in a single view.
Low cost to own and run
Light on resources, simple to operate, and it scales from one site to many without a rebuild. Low TCO is designed in, not discounted in.
Fits the tools you already use
An open, standard API means alerts and data land in your existing service desk, SIEM or NOC screen instead of another silo.
Support that actually answers
Direct access to the engineers who build the product, backed by a service agreement — not a queue and a ticket number.

Two editions. Pick where you hurt most.
Keep the network healthy, protect it from what should not be there, or run both together on the same engine.
NM-Network Monitoring
Everything you need to keep a large network healthy: it finds your devices, maps them, watches them around the clock, and tells you what is wrong before your users do. The sniffer is included for online capture and analysis when you are chasing a problem — in short sessions rather than continuously.
- Device availability
- Automatic network discovery
- Physical device location discovery
- History & online performance graphs
- Logical & physical mapping
- Sniffer online capture & analysis — short sessions
- Physical error detection
- AI machine learning
Licensed on
- Ports
- How many ports on the network
- WAN lines
- How many WAN lines you run
- Installations
- How many sites or data centres
Best for IT and network operations teams responsible for uptime across several sites.
NM-Security Cyber
Here the sniffer never stops. It records around the clock and keeps what it records, so when something happens you can go back to any moment and see exactly what took place — then feed it straight into the security tools you already run.
- Real-time anomaly detection
- Sniffer recording packets 24/7 — continuous, never stops
- Saving data for future research
- Interfacing to external systems
- Historical search of stored data
